The MMBT3904 is a general-purpose NPN bipolar junction transistor (BJT) housed in a compact SOT-23 SMD package. It is widely used in switching and amplification applications due to its high current gain, low saturation voltage, and fast switching capabilities. Designed for low-power surface-mount designs, this transistor is ideal for signal processing, driver circuits, and general-purpose electronic projects where board space is limited.
Features of MMBT3904 NPN Transistor:
- General-purpose NPN transistor for low-power applications
- Fast switching speed suitable for high-frequency operations
- High current gain (hFE) for improved amplification
- Low collector-emitter saturation voltage for efficient switching
- Compact SOT-23 SMD package suitable for dense PCB layouts
- Ideal for digital and analog switching circuits
- RoHS compliant and lead-free construction
